Strength of Materials The angle which an inclined plane makes with the horizontal when a body placed on it is about to move down is known as angle of friction repose limiting friction kinematic friction friction repose limiting friction kinematic friction ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials Least force required to draw a body up the inclined plane is W sin (plane inclination + friction angle) applied in the direction at an angle equal to the angle of friction to the inclined plane vertically along the plane horizontally at an angle equal to the angle of friction to the inclined plane vertically along the plane horizontally ANSWER DOWNLOAD EXAMIANS APP
